One of the best ways to spot an opportunity is by paying attention to insider activity, particularly insider buying. After all, it is the insiders who know their company the best – and if they’re buying, pay close attention.

Oftentimes, there’s a good reason for their buying spree. Here are a few stocks you may want to keep an eye on now.
Insider Buying Stocks: CoStar Group
Commercial real estate giant CoStar Group (NASDAQ: CSGP) has plunged since the stock hit approximately $70 a share in late December 2025. Now at $48.38, two activist investors, including D.E. Shaw and Third Point, want the company to scale back its investments in Homes.com. Plus, it’s seeing healthy insider buying.
As noted by Barron’s, “Both activist firms previously secured board seats and created a capital allocation committee in 2025, but they argue those changes haven’t improved performance. Third Point renewed its campaign in January, with CEO Daniel Loeb calling the board ‘feckless’ and demanding a change in strategy.”
CoStar doesn’t invest in commercial real estate directly. Rather, it’s a provider of information, analytics and online marketplaces for the commercial real estate industry. The company gathers property-level data, builds market analytics and supplies research tools used by brokers, owners, lenders, investors and other real estate professionals to evaluate markets, track inventory and manage listings.
Board director Rachel Glaser just bought 1,000 shares for $44.94 a share for $197,873. President of Marketplaces Fred Saint bought 20,000 shares on March 1 at an average price of $45.33 for about $906,600. CEO and Founder Andy Florance also picked up 55,720 shares for $44.52 a share for about $24.8 million.
Insider Buying Stocks: KKR & Co.
Private credit has been getting destroyed in 2026. And as one of the leading names in the space, KKR & Co. (NYSE: KKR) has been a tough stock to own. KKR stock is down about 34% in the three months ending March 6. However, the crushed shares are getting some insider support.
Specifically, after the stock dropped from about $135 to less than $90, Co-CEOs Joseph Bae and Scott Nuttall purchased a combined $8.8 million worth of KKR stock last week. “In total, the board members and co-CEOs have purchased more than $46 million worth of shares since Feb. 11,” added Barron’s.
“These purchases reflect our leadership team’s strong confidence in our future performance,” a KKR spokesperson told Barron’s.
Insider Buying Stocks: SoFi Technologies
Insiders are also buying SoFi Technologies (NASDAQ: SOFI) after a post-earnings dip. Rob Lavet, general counsel, bought 5,000 shares for about $21.04 each. Eric Schuppenhauer, the head of borrowing, picked up 5,000 shares at $19.93 per share.
That kind of buying makes sense for a couple of reasons. First, as of March 9, SOFI stock is technically oversold at $20.40.
Second, the stock was recently upgraded by analysts at JPMorgan Chase (NYSE: JPM) to overweight. The firm said, “Momentum in the business is undeniable, as SoFi continues to add new members and deposits at a record pace, while other fintechs report deposit outflows or stagnant member growth, and investments in marketing in ‘25 and 1H26 set the stage for continued premium customer acquisition and engagement for the foreseeable future,” as quoted by Seeking Alpha.
Insider Buying Stocks: Ares Management
Director Ashish Bhutani just bought 10,000 shares of Ares Management Corp. (NYSE: ARES) for about $1.27 million. ARES was also upgraded to a Buy rating at Deutsche Bank (NYSE: DB) after fourth-quarter earnings.
“While the Q4 results presented a headline miss on realized income, we believe the market’s concerns regarding private credit fundamentals and potential AI disruption are overblown relative to (the) likelihood of durable FRE (fee-related earnings) growth remaining intact across our forecast horizon,” said the analysts as quoted by Seeking Alpha.
“We see several key tailwinds for 2026. First, mgmt. expects fundraising to remain robust in 2026, citing an expectation for total fundraising this year to meet or exceed records in 2025. Second, the outlook for FRE margin expansion was reaffirmed on the call, as management guided to the high end of its 0-150 bps annual expansion target range, supported by synergies from the GCP integration, improving operating efficiencies, with the data center business becoming a positive FRE contributor.
Making ARES even more attractive, it just declared a $1.35 per share dividend, which is payable on March 31 to shareholders of record as of March 17.
Insider Buying Stocks: Lumen Technologies
Over at Lumen Technologies (NYSE: LUMN), CEO Kathleen Johnson just bought about $500,000 worth of stock, picking up 76,685 shares. “Kate Johnson’s recent open-market stock purchase reflects her continued confidence in Lumen’s long-term strategy and the value the company is creating through its transformation,” said the company, as quoted by Barron’s.
“This is not the first time Kate has personally invested in Lumen shares, underscoring her strong belief in the company’s future as a digital networking services leader driving enterprise growth and innovation for a multi-cloud, AI economy,” they added.
